How To Keep Your Cast Iron Skillet Alive Forever

It's time to season your pan like a grown-up

If I were exiled to a desert island with one piece of cookware, I wouldn’t hesitate. Give me my 10-inch cast iron skillet and I’ll fry fish over a driftwood fire like a caveman who just discovered bacon. For me, a cast iron pan isn’t just a pan—it’s a ride-or-die. It’s the steak-searing, cornbread-baking, heirloom-worthy kitchen weapon that only gets better with age.

But here’s the thing they don’t tell you when you first fall for it: it’s high-maintenance. Not in a diva way, but more in a “treat me right and I’ll love you forever” way. Think of it less like a nonstick fling and more like a long-term relationship. So here’s the straight-shooting, no-fuss guide to keeping your cast iron skillet alive, seasoned, and sizzling.

The Golden Rules

Let’s start here: don’t leave it in the sink. Not for five minutes. Not overnight. Cast iron doesn’t like moisture the way your ex doesn’t like accountability. It rusts. And oh boy, it rusts fast.

Also, don’t put it in the dishwasher—not unless you’re actively trying to destroy it (in which case, may I interest you in some Teflon?). And please, don’t reach for steel wool unless you like scraping off a decade of built-up seasoning.

There’s a lot of lore around cast iron. Some of it useful. Some of it deranged. Like the whole “never use soap” thing? Relax. Mild dish soap isn’t going to nuke your seasoning. You know what will kill your pan? Leaving it wet.

The Chill Clean-Up Routine

Here’s what you actually do after cooking:

  1. While the pan is still warm, rinse it under hot water.

  2. Scrub gently using a non-abrasive sponge or brush. No fancy tools required—just something soft that won’t wreck the seasoning. If you got some stuck on bits, just toss in some kosher salt and a few drops of water and scrub away. It’s like a facial for your skillet.

  3. Dry completely. I mean completely. Wipe it with a towel, then stick it on low heat on the stove for a few minutes to get every last drop of moisture out. This step is fully non-negotiable.

  4. Oil it up. Once dry, rub in a few drops of neutral oil—canola, vegetable, grapeseed, whatever’s within arm’s reach. Wipe it all over with a paper towel or cloth. Inside, outside, handle, the whole shebang.

For the oil, you want the surface to look matte, not slick. The black patina that makes your pan non-stick, rust-proof, and beautiful. If the surface ever starts looking dull or patchy, that’s your cue: oil it up and throw it in a hot oven (450°F) for an hour. Let it cool in there. That’s how you build layers and that’s how it becomes heirloom.

So You F*cked Up and Now It’s Rusty

It happens. Maybe you forgot. Maybe a well-meaning houseguest washed it and left it out to “air dry” (bless their heart). Don’t worry, maybe it’s not dead.

  • For light rust, scrub with the rough side of a sponge and dish soap. Yes, soap.

  • For heavy rust, submerge it in a 1:1 mix of vinegar and water. Set a timer. Don’t let it sit more than 8 hours or it might start dissolving your pan. Once the rust’s gone, rinse, dry, and—say it with me—re-season.

And how do we go about re-seasoning? It’s simple. Crank your oven to 475°F and rub a thin layer of neutral oil all over. Bake it upside down for an hour and then turn off the oven and let it cool inside. See, it’s not that hard?

Cast iron isn’t hard. It’s just… honest. Treat it like a reliable old motorcycle: ride it often, clean it with care, give it oil, keep it dry. Skip the drama. Skip the gimmicks. And you’ll be using it for a long, long time.
